The Mimosaceae are mostly tropical and subtropical trees and shrubs comprising about 40 genera and 2,000 species. The leaves are nearly always alternate, stipulate, and bipinnately compound (rarely once-pinnate) They usually have swollen petiole bases called pulvini that commonly function in orientation of the leaves (remember the sensitive plant, Mimosa pudica). The inflorescence is commonly a capitulum (also called a head). The flowers are hypogynous to slightly perigynous, have radial symmetry, petals that are valvate in bud, and commonly a 5-parted calyx and corolla. The stamens are distinct to strongly monadelphous, numerous (rarely as few as 10), and are generally more showy than the perianth. The pistil is simple, comprising a single style and stigma, and a superior ovary with 2-many marginal ovules in a solitary locule. The fruit is usually a legume. -- Gerald Carr

Adenopodia is a genus of legume in the Fabaceae family. It contains the following species: [more]
Balizia is a town and sub-prefecture in the Macenta Prefecture in the Nz?r?kor? Region of south-eastern Guinea. [more]
Chloroleucon is a genus of flowering plants in the pea family, Fabaceae. Some authorities consider it part of the genus Albizia. The generic name is derived from the Greek words ?????? (chloros), meaning "green," and ?e???? (leukos), meaning "white." [more]
Geoffroea is a rather small genus of wild spiny shrubs or small trees of tropical and subtropical South America. Although it gathers few species, they are highly extended geographically throughout the subcontinent. Each species is well known in its local area, as seen from the varied (and mostly domestic) usage of these trees as food, timber or fuel. [more]
Hydrochorea is a legume genus in the subfamily Mimosoideae. It contains a mere 3 species at present: [more]
Inga is a of tropical trees and shrubs, member of the infrafamily Ingeae. Inga's leaves are pinnate, and flowers are generally white. Many of the hundreds of species are used ornamentally. [more]
Racosperma is a name proposed for the 980 odd Australian members of the genus Acacia which belong to the subfamily Mimosoideae of the Pea Family Fabaceae, first described from Africa by C. F. P. Martius in 1829. [more]
At least 17 species and subspecies belong to the Genus Samanea.
